@RichtoffenRoach I'm no physicist but atoms cannot be seen with visible radiation (light) because they don't reflect it. They can be seen via other wavelengths and frequencies of the electromagnetic spectrum.

@NANOFORGE So those pictures about atoms that i've seen is a lie? How can they play with them? Nanotechnology! Ca you please enlighten me?

@RichtoffenRoach Atoms cannot be seen because they don't relect light (they are too small). They can be measured and detected in many ways, I.e through their radioactivity etc, you should read up on it.

@pirskwayrd Um...alpha particles have positive charges. Beta has negative charges. XD
Such an amazing scientist Sir Ernest Rutherford was. This one person made so many discoveries!!!

No, that's because the outter shell of every atom is comprised of electrons which all have a negative charge. Like charges repel.
